Radiographic Studies
Fluorescein angiography (figure 3) demonstrated hypofluorescence of the lesions due to blockage of dye transmission by the yellow deposition material.
A scotopic and photopic full-field ERG were normal. An EOG was markedly depressed (Arden ratio of 1.3 in both eyes ).
The results of a complete blood workup were negative except for elevated hepatic enzymes. Further investigations led to the diagnosis of hepatitis C. No risk factors were established.
